tional view from front to rear of the structure. from side to side of the structure.

One object is to provide a new and novel base for spring structures embodying means whereby the spring supporting wires may be readily secured thereto together with the side facings of the coverings of the structure.

Another object resides in the provision of a base frame constructed whereby the front, rear and side facings of the upholstering covering may be readily secured thereto.

With the above and other objects in view the present invention consists in the combination and arrangement of parts hereinafter more fully described, illustrated in the accompanying drawings and particularly pointed out in the appended claims, it being understood that changes may be made in the form, proportion, size and minor details without departing from the spirit or sacrificing any oft-he advantages of the invention.

In the drawings :Figure 1 is an inverted plan view of a spring structure illustrating my invention with the springs of the struc- Fig. 2 is a transverse see- Fig. 3 is a transverse sectional View l-leferring now more particularly to the accompanying drawings, the reference char actor indicates an upper frame formed preferably of wire and lla base frame formed preferably of sheet metal. These lrarncs extend entirely around the spring structure with the lower frame preferably consisting of upper and. lower flanges rt and 7/. respectively. connected at their inner edges by thewcli ll 'forniiug a channel or grhove 10 with the lower flange portion of the channel having its free edge directed dowi'nvardly as at 1:2 and inwardly'as at 13 to form a supportfor the spring supporting wires l-l which, as shown, are preferably continuous supports curved at opposite ends Specification of Letters Patent.

with their curved ends fitted on the supportmg portions 13 and clamped tl'ierebetween and the under side of the flange portion 5 of the base frame so that the supporting wires 1 may be held firmly with relation. to the base frame. If desired the inner edge of the wire supporting portion 13 may be directed inwardly at intervals as indicated at 15 to lap over the curved ends of the sup porting wires to further secure them to the base frame.

Mounted upon the supporting wires let are the springs 15, they being secured to the supporting wires 14 by means of any suitable clips 16. These springs 15 may be arranged in any suitable manner and may be of any suitable type of springs, and as illustrated in the accompanying drawings, the front row of springs are preferably formed of superimposed springs 17 and 18, the springs 17 and 18 being connectedtogether by means of suitable clips 19. If desired, flexible bands 20 may be secured to the tops of the springs and at their forward ends directed downwardly as at 21 and inwardly as at 22 and connected to the clips 19, the portion 21 of each band projecting slightly beyond the front of the structure to provide for a flexible roll at the upper front edge of the seat. While this particular arrangement of springs and bands 20 is illustrated in the accompanying drawings, 1 do not claim to be the inventor thereof.

Fitted in the channel or groove 10 on the sides, front and rear of the base frame B, 1 preferably dispose a wood insert 23 which may be held in the channel by means of suitable fastenings Eat. This wood insert is adapted to form means whereby the front, rear and side facings of the upholstcring covering-may be readily secured to the base frame without the necessity and consequent expense involved in having the side facings secured to bottom facings in the usual manner. The aforesaid flange a of the groove or channel 10 forms a shoulder with which the wood insert 23 coilpcratcs to. hold the side facing of the upholstering material against upward tension of the springs 15.

In actual practice canvas or other fibrous strips i i are fitted over the bands 20 and are continued downwardly at the front of the structure as at 2?. Spread over the top of the structure and around the bowed part :21 of the bands 20 is hair or other upholstering material 28 with the top facing 29 sewed or otherwise secured at 30 to the front, rear and side facings 25 and to the by means of upholsterlng tacks'3l driven.

into the outer sides of the wood insert and through the facings and canvas strips, whereby the facings are held against upward movement and an ornamental finish given the structure.

From the foregoing it will be seen that I provide an exceedingly simple base frame and one which possesses in addition to other characteristics means whereby the fa'cings may be secured effectively thereto arid the spring supporting wires also secured thereto so that the base frame performs a dual function and has cooperation both with the side facings and with the support of the spring supporting wires.

What is claimed is: v

1. In a device of the character described, a base frame comprising a metallic member provided with oppositely disposed outwardly directed flanges which form a continuous surrounding groove which opens outwardly horizontally, said metallic member also having an inwardly directed flange of less width than the width of said other flanges and with the lowermost of the aforesaid flanges forming a relatively narrow continuous tightly in the outer groove, and

groove which opens inwardly horizontally under the lowermost of'the first mentioned flanges,a filling of wood which is substantially rectangular in cross section fitted s ring supporting wires having their ends disposed in said inner groove said last-mentioned flange of the base frame being directed inwardly with relation to the groove at intervals to clamp the ends of said wires in the inwardly opening groove.

2. In a device of the character described, a base frame comprising a sheet metal memher provided withoutwardly directed oppo sitely disposed fianges which formas con tinuous surrounding groove which" opens outwardly horizontally, and also having an inwardly directed flange which cooperates with the lowermost of theoutwardly 'directed flanges to form a relatively narrow continuous groove which opens inwardly horizontally, a filling of wood disposed tightly in the outer groove, and spring supporting wires having their ends disposed in said inner groove, the last-mentioned flange being upset at intervals to clamp the ends of the said wires in the inwardly opening groove.

In testimony whereof I affix my signature in presence of two witnesses.
